STARTING AND DRIVING
}}
* Option/accessory, for more information, see Introduction. 377
NOTE
•
When parking the vehicle with a trailer on
a hill, apply the parking brake before put-
ting the gear selector in
P
. Always follow
the trailer manufacturer's recommenda-
tions for wheel chocking.
•
When starting on a hill, put the gear
selector in
D
before releasing the parking
brake.
•
If you use the manual (Geartronic) shift
positions while towing a trailer, make sure
the gear you select does not put too
much strain on the engine (using too
high a gear).
•
The drawbar assembly/trailer hitch may
be rated for trailers heavier than the vehi-
cle is designed to tow. Please adhere to
Volvo's recommended trailer weights.
•
Avoid driving with a trailer on inclines of
more than 15%.
CAUTION
The maximum trailer weights listed are only
applicable for altitudes up to 3,280 ft
(1000 m) above sea level. With increasing
altitude the engine power and therefore the
car's climbing ability are impaired because of
the reduced air density, so the maximum
trailer weight has to be reduced accordingly.
The weight of the vehicle and trailer must be
reduced by 10% for every further 3,280 ft
(1,000 m) (or part thereof). When towing
5,000 lbs (2,250 kg) hill inclination is restric-
ted to 14%.
WARNING
•
Bumper-attached trailer hitches must not
be used on Volvos, nor should safety
chains be attached to the bumper.
•
Trailer hitches attaching to the vehicle
rear axle must not be used.
•
Never connect a trailer's hydraulic brake
system directly to the vehicle brake sys-
tem, nor a trailer's lighting system directly
to the vehicle lighting system. Consult
your nearest authorized Volvo retailer for
correct installation.
•
When towing a trailer, the trailer's safety
chains or wire must be correctly fastened
to the attachment points provided in the
trailer hitch on the vehicle. The safety
chain or wire must never be fastened to
or wound around the towing ball.
Trailer cable
An adapter is required if the vehicle's trailer hitch
has a 13-pin connector and the trailer has 7 pins.
Use an adapter cable approved by Volvo. Make
sure the cable does not drag on the ground.
Self-leveling suspension
*
With this system, the rear suspension maintains a
constant level, regardless of the load in the cargo
compartment (up to the max. permissible load).
When the engine is not running, the rear of the
vehicle sinks down slightly, which is normal.
